“How can patients feel safe amid fleas, rats and even cockroaches being found in our hospitals. These findings reveal what happens when money is taken away from where patients expect to see it spent. Wards are where we should see a nurse or a doctor and not a rat trap. It is horrifying that our hospital buildings are in such a ramshackle state.”

Royal Wolverhampton NHS Trust spokesman Richard Radcliffe, said: "We always strive to provide high quality, safe care for our patients. We take pest control very seriously and all our sites are routinely maintained and kept as pest-free as possible."
